All you can do, in therapy or out, is start from where you are and notice what's there for you. That often starts with noticing that you think something should or could be there, being willing to let that thought go, and noticing what's up for you next.

Blue, if "something" is blocking you, notice where it's located for you and how you tell it's actually there.

You can clear a "something" out of your way either by noticing carefully what it looks like, feels like, sounds like, and how you experience it -- or by recognizing that it's just a thought you're having, that it exists only because you're thinking it, and that it's only in your way as long as you're putting it there.

Maybe some clients find interpretations like that doc's useful --

... when you “clam up” in psychotherapy you exhibit a resistance to doing the work, and this points to an unconscious anger at your father for his failing to help you when you needed help.

I've often caught myself thinking I "should" (find them useful) and there's something wrong with me if I don't, but in fact I don't think I ever have. My parents were the way they were and I reacted to them however I did. That was then. If I clam up or I don't, I experience intimacy or I don't, that's now, and the only way I've ever found to deal with it is to start from exactly where I am, notice what I'm choosing, and just keep telling the truth about it.

Your mileage may vary but I'll be surprised if it does and I hope you'll tell me about it.
